Strange description in datasheet of STPMIC1

In p. 28 of Datasheet - STPMIC1 - Highly integrated power management IC for micro processor units, 4.2.1, it says:

3. Manually by setting VOUT[4:0] field of Table 38. BUCKx_MAIN_CR or Table 43. BUCKx_ALT_CR registers. Refer to Table 9. LDO output voltage settings.

Does it mean the BUCK regs will determine the LDOs' VOUT?????

Thanks.

    Thank you very much for reporting this typo.

    The line:

    • Manually by setting VOUT[4:0] field of Table 38. BUCKx_MAIN_CR or Table 43. BUCKx_ALT_CR registers.

    should be read as:

    • Manually by setting VOUT[4:0] field of Table 40. LDOx_MAIN_CR or Table 45. LDOx_ALT_CR registers.

    It will be corrected in one of the next updates of the datasheet.

    Regards

    /Peter
